On servers with not too much memory ("only" 16 GB), dovecot logins fail:
Nov 25 21:35:15 server dovecot[28737]: master: Fatal: setrlimit(RLIMIT_DATA, 268435456): Permission denied
Nov 25 21:35:15 server dovecot[28731]: master: Error: service(auth): command startup failed, throttling for 2 secs
Nov 25 21:35:15 server dovecot[28737]: auth: Fatal: master: service(auth): child 25976 returned error 89 (Fatal failure)
audit.log messages are:
... apparmor="DENIED" operation="capable" profile="/usr/sbin/dovecot" pid=25000 comm="dovecot" capability=24 capname="sys_resource"
... apparmor="DENIED" operation="setrlimit" profile="/usr/sbin/dovecot" pid=25000 comm="dovecot" rlimit=data value=268435456
After allowing capability sys_resource, dovecot can increase the limit
and works again.
